Press Release: Okefenokee National Wildlife Refuge

When the three-quarter mile long boardwalk on Okefenokee’s Chesser Island was devoured by the Honey Prairie Fire on June 13, 2011, the National Wildlife Refuge lost one of its most treasured assets. Nearly two years later, work is underway to replace this walkway into the swamp. Hydra Engineering and Construction, LLC, of Crawfordville, Florida, designed the new boardwalk and began mobilizing on site February 26. Materials began arriving a month ago, and the first few yards of the planking are now in place. The anticipated completion date of the project is early August.

The wooden boardwalk will be rebuilt using Trex, a wood polymer product. Trex uses recycled plastic grocery bags and stretch film, as well as waste wood from making furniture and shipping pallets. This recycled materials product illustrates the U.S. Fish and Wildlife Service’s commitment to using “green construction” whenever possible.

Joists will be of pressure-treated lumber, and galvanized helical piers with aluminum beams will provide added fire-resistance. A pioneering sprinkler system will be employed to prevent destruction by all but the hottest fires. A 3,700 foot waterline will service 88 sprinkler connections placed every 40 feet, from the bathrooms at the parking lot to the top of the observation tower.

The boardwalk will follow the same path as the old one, and when the boardwalk reaches the end at Seagrove Lake, the Owl’s Roost tower will be repaired with pressure-treated lumber. Damaged wooden supports on the tower will be replaced with steel to make it stronger and more tolerant to future fires. The new boardwalk will also be eight feet wide, and like the old one, will not have a railing – providing an unobstructed experience with the swamp landscape and wildlife. It will also have four 16x16 foot covered pavilions with benches.

In addition, the boardwalk will be made to support up to 13,000 pounds of maintenance equipment for mowers and the like. Leslie Hope, owner of Hydra Engineering and Construction, says a unique aspect to this boardwalk is the “top down construction” method. The boardwalk will be built as-you-go – meaning minimal disturbance by not having a lot of equipment in the swamp. “It minimizes impact to the environment,” said Hope. “We have pictures of ducklings that hatched while we were building the boardwalk at Chattahoochee River National Recreation Area, and they adopted our construction crew. They were swimming between their legs as they worked.” It is a method that requires more effort, she said, but it is one “frequently used by us.”

The Chesser Island boardwalk provided one of the only good walking-access views into the swamp, and it has been sorely missed. Visitors began the trip from the pine uplands of Chesser Island, traveling through the transition zone of scrub-shrub before reaching the open marsh areas. Then they walked onto a cypress dome before ascending the 40-foot Owl’s Roost Observation Tower with its expansive view of Chesser Prairie. Pairs of resident Florida sandhill cranes could often be seen with their young only 50 feet from the boardwalk. Of course, alligators and turtles would be much closer, and other wildlife and a variety of birds would be seen. It was an intimate experience of swamp life that could be had without getting one’s feet wet.

It was also a rite of passage for many school groups, whose visit to the refuge wasn’t complete without making the trip down the boardwalk. It was the primary outdoor classroom for the refuge, both informally, and through formal ranger-led interpretive and environmental education programs. Locals used it for their daily exercise and socializing, and visitors would even set up easels and paint “plein air.” These are experiences that will return upon completion of the famed boardwalk.

Because the fire cleared out many trees, the view will be reminiscent of when the boardwalk was completed in 1970. The parking lot and restrooms at the trailhead will be closed until construction is completed.
